SES SMTP User

Provides SMTP credentials for an existing SES domain identity.

SMTP usernames and passwords for SES require creating an IAM user and access key. This module will create a Secrets Manager secret and populate it with rotating SMTP credentials from a dedicated IAM user.

Example:

module "ses_smtp" {
  source = "github.com/thoughtbot/terraform-aws-ses-smtp-credentials?ref=v0.2.0"

  # The domain corresponding to your domain identity
  domain          = "example.com"

  # The name of the secret to create
  name = "example-production-smtp"

  # Fill in details for your VPC
  subnet_ids = data.aws_subnet.private.*.id
  vpc_id     = data.aws_vpc.this.id
}

The outputs include policy_json, which is an IAM policy allowing access to the secret. You can add this to an IAM role or policy.
